Wash peppers..cut large ones in half lengthwise...remove a slice from stem end of small ones. Remove seeds and cut away seed parts, leaving a clean shell.
Place in boiling, salted water and boil for 5-8 minutes, or until almost tender. Drain.
Stuff each pepper with stuffing. Place in a shallow baking dish containing a small amount of water.
Bake at 375º for 25-30 minutes or until browned.
Brown beef slightly, stirring to keep meat in separate particles. If the meat is lean, I add a little fat. Add onion and celery and cook about 5 minutes longer or until vegetables are soft.
Add ground ham, rice and season to taste. Moisten with a little bit of the tomato sauce.
Fill pepper shells. Before baking, pour remaining tomato sauce over shells.
